12 Claims.

This invention pertains to railway car construction and more particularly to carry iron wearing plates.

In general it has been found that couplers in use in railway rolling stock are not held. exactly horizontally, it being found that there is more or less dropping down of the coupler head. This, of course, causes the coupler shank to be angularly disposed with respect to the carry iron wearing plate disposed on the striking casting so that the support of the coupler is not over an appreciable surface, but only over a line. Such relative position is undesirable as excessive stress concentration results, and unequal and weakening wear occurs in the structures. Continuous longitudinal movement of the coupler shank causes undue wear at only the contact, necessitating expensive replacements. i

It is an object of this invention to provide a construction wherein the wearing contact between the coupler and its wearing plate or bearing is substantially constant and is over an appreciable surface.

Another object of this invention is to provide an economical wearing plate construction for coupler construction which is operable in any position of the coupler. i

A further object is to provide a wearing plate construction interchangeable with the present construction and one which in repair will compensate for wear on' the associated structure and relieve excessive droop of the coupler structure.

With these and various other objects in view,

the invention may consist of certain novel features In the drawing, which illustrates an embodi- I ment of the device and wherein like reference characters are used to designate like parts- Figure 1 is a sectional elevation of the striking casting provided with the improved wearing plate showing the position of the coupler in horizontal position;

Figure 2 is a view corresponding to Figure 1 showing the coupler in drooped service position;

Figure 3 is an enlarged sectional elevation showing the improved rocker wearing plate supported on a portion of the striking casting, the same corresponding to Figure 1.

The car draft sills are shown provided with the striking casting riveted thereto as at 14, said striking casting being shown with integral cheek plate portions 16 provided with keyways 18 for the reception of the transverse key 20 received in keyways 22 provided in the coupler shank 24. The striking casting is apertured as at 26 for receiving the coupler shank, the upper portion being provided with the inwardly directed flange 28, and the lower supporting or carrier portion 30 being preferably of inverted U-shape having a fiat-topped web 32. The web 32 forms a bearing or support for the inverted substantially U-shaped or channel shaped rocker'wearing plate 34 disposed between the portion 30 and the coupler shank. The plate 34 is disposed to embrace the portion or member 30, having depending arms or legs 36 and 38 and a shank engaging web 40, the legs serving to engage the support to limit the rocking of the wearing plate. These arms 3638 retain the wearing plate 40 in operative engagement with the portion 30 of the striking casting as the coupler moving back and forth in service tends to take the plate 34 with it. The upper surface 42 of the web 40 is substantially fiat, but the lower surface 44 of said web is curved or arcuate to provide a rolling action of said plate upon drooping of the coupler head, such as shown in Figure 2. The inner surfaces of the arms 36 and 38 are flared outwardly relative to each other so as to loosely engage the portion 30 in any service position of the wearing plate relative to the portion 30. 'Of course, the upper surface of the portion 30 may be curvedupwardly and the lower surface of the web 40 made flat and still come within the scope of the invention.

In order to give a slightly longer bearing surface 42, u1e leg 38 may bethickened as at 48. However, with the thicker plate greater stiffness is secured, and in repair or replacement work this thickness will compensate for the wear.

It will thus be seen a very advantageous construction is provided, and it is to be understood that I do not wish to be limited by the exact embodiment of the device shown, which is merely by way of illustration and not limitation, as various and other forms of the device will of course be apparent to those skilled in the art without departing from the spirit of the invention or the scope of the claims.

I claim:

1. In a draft appliance, the combination of a stationary coupler supporting member, said member having a plane supporting surface, a coupler having a shank, and a wearing plate having a plane coupler engaging surface and provided with a curved surface engaging the plane surface of said member.

2. In a draft appliance the combination of a stationary coupler supporting member, said member having a plane supporting surface, a coupler having a shank and a wearing plate having a top plane coupler engaging surface and an under curved surface engaging the plane surface of said support.

3. In a draft appliance the combination of a coupler supporting member, a coupler shank, and a wearing plate having supporting engagement with said shank and member, said plate having surface contact with said coupler shank, and being provided with means. for maintaining said surface contact between said shank and plate regardless of the vertical angling of said coupler on said wear plate as a fulcrum.

4. In a draft appliance the combination of a coupler supporting member, a coupler shank, and a wearing plate having supporting engagement with said shank and member, said plate having surface contact with said coupler shank, and being provided with a curved surface engaging said supporting member whereby said plate is movable during vertical angling of said coupler on said wear plate as a fulcrum for maintaining said surface contact between said shank and plate.

5. In a draft appliance, the combination of a coupler supporting member, a coupler shank, a wearing plate having supporting engagement with said shank and member, said plate having surface contact with said coupler shank, and being provided with means for maintaining said surface contact between said shank and plate regardless of the vertical angling of said coupler on said wear plate as a fulcrum, and means for limiting the movement of said plate.

6. In a draft appliance, the combination of a coupler supporting member, a coupler shank, a wearing plate having supporting engagement with said shank and member, said plate having surface contact with said coupler shank, and being provided with a curved surface engaging said supporting member whereby said plate is movable during vertical angling of said coupler on said wear plate as a fulcrum for maintaining said surface contact between said shank and plate, and means for limiting the movement of said plate.

7. In a draft appliance, the combination of a coupler supporting member, a coupler shank, a wearing plate having supporting engagement with said shank and member, said plate having surface contact with said coupler shank, and being provided with a curved surface engaging said supporting member whereby said plate is movable during vertical angling of said coupler on said Wear plate as a fulcrum for maintaining said surface contact between said shank and plate, said plate being provided with leg portions embracing said coupler supporting member for engagement therewith for limiting the movement of said Plate.

8. In a draft appliance, the combination of a coupler support having a supporting surface, and a wearing plate having a top flat coupler carrying part and an under surface engaging said supporting surface one of said surfaces being curved so as to provide a rolling action of said wearing plate upon said support upon drooping of the coupler head.

9. In a draft appliance, the combination of a coupler support having a supporting surface, and a'wearing plate having a top flat coupler carrying part and an under surface engaging said supporting surface one of said surfaces being curved so as to provide a rolling action of said wearing plate upon said support upon drooping of the coupler head, said wearing plate having depending arms embracing said support so as to retain the plate in operative engagement with.
